Two shades from the same conversation. The med heather gray carries the gray that works with everything, the space black anchors it with black's more interesting sibling. Technical fabric with a dry hand feel and real pockets. Boarding group 2. You didn't check a bag and you don't look like it. When your outfit doesn't wrinkle, you stop worrying about the flight. You just take it.
Finish with matte black leather sneakers and a black nylon duffel.
